Pros : Simple clean room for a solo traveler, with private bathroom. Very affordable and convenient : only a 3 minutes walk to Udomsuk BTS station, plenty of local food nearby and on the other side of Sukhumvit.
Cons : If you're 1m90 or taller you'll feel the ceiling is a bit low. The space is not ideal if you plan to work long hours in the room (small table and mainly artificial light).
